Cell phone battery currents create magnetic field pulses that stay within safety guidelines, but add to your total EMF exposure.

Plain English Summary

Summary written for general audiences

Finnish researchers measured the magnetic fields produced by battery currents in seven different cell phone models to determine if these fields pose health risks to users' heads. They found that while the phones create measurable magnetic field pulses when transmitting, the exposure levels remained well below international safety guidelines. The study concluded there's currently no biological evidence suggesting these magnetic field pulses from phone batteries cause health problems.
